The AirTAC GC400C10LF2GK AirTAC F.R.L. Combination, G3/8 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
GC400C10LF2GK is an AirTAC GC three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 400 unit carries a G3/8 (BSPP) port, a 40 um filter element with a differential-pressure drain, a low-pressure type regulator with an embedded square gauge scaled in psi, a reverse (check) valve, and a mounting bracket. The filter bowls are polycarbonate at this size. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of drain type, 40 um or 5 um (W) filtration, gauge scale (MPa, psi or bar), reverse valve, and thread (PT standard; G and NPT to order). Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-C1 filter, GR400-C1 regulator and GL400-C1 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeding low-pressure air to spray guns and air-assist circuits on a paint line: the filter removes water and particulate, the low-pressure regulator holds a gentle set pressure, and the lubricator mists oil to downstream air tools.
Supplying treated air to carton-sealing and case-erector cylinders along a packaging conveyor, where one three-unit set conditions the whole drop instead of three separate components.
Conditioning air for pneumatic clamps and tool-change actuators on a machining centre: clean, regulated, lubricated air at the machine helps the clamping circuit behave consistently shift after shift.
The real choices in this series are decodable from the code. Step size first: 200, 300, 400 and 600 move up in port and flow capacity, so match the size to the air demand of the circuit rather than to the pipe alone. Drain type: differential-pressure (the default on this unit), automatic (A) or manual (M). Filter grade: 40 um standard, 5 um with W. Gauge: embedded square as standard with MPa, psi or bar scales, or an external round gauge. Thread: PT is the standard; G (BSPP) and NPT are order options - this unit is specified with G3/8. A mounting bracket is included and a reverse/check valve is fitted (K). Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm the right size before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your required flow and working pressure and we will confirm from the datasheet whether GC400 at G3/8 suits your application before you order.
This GC400 unit is built with the low-pressure type regulator. Its exact regulation range is not published in the catalogue, so if you need to hold a specific low set pressure, ask us to confirm the low-pressure range from the datasheet before ordering. The embedded square gauge on this unit is scaled in psi.
